Most teams now seem to play a variation of 4-5-1, a system that suits City and Aguero who seems to prefer being up front on his own. It is OK to have a Dzeko type of back up player for specific games, or to bring on in late stages of games where our tactics aren't quite going to plan and we need a Hail Mary escape route. Other than that, the only type of striker I would want us to pursue is another Aguero, easier said I know, but it worked with Aguero and Tevez and both players could play up top on their own or together if need be, and if we could find someone with the same characteristics as these two, we'd be well set up.
